【Validation】3 validations

Problem

Do 3 validations

Wrong Coding

a = input()
while unwanted_condition 1:
    a = input()
while unwanted_conditino 2:
    a = input()
while unwanted_condition 3:
    a = input()

Correct Coding

Method 1

a = input()
 while True:
    if wanted_condition_1 and wanted_condition_2:
        if wanted_condition_3:
            break
    a = input()

while True + if condition + break = REPEAT and UNTIL command

Method 2

a = input()
while unwanted_condition_1 or unwanted_condition_2 or unwanted_condition_3:
    a = input()
